Gemstones – What You Need to Know

When it comes to gemstones, there are many factors that go into choosing one. Color zoning, hardness, translucency, and meanings are just a few of the factors that we’ll cover in this article. But before we dive in, let’s review the most important details. First, what is a gem? There are literally thousands of varieties, and it is crucial to know what each one stands for. After all, it’s not just a pretty stone – there is meaning behind its color, too.

Color zoning

The natural distribution of color in a gemstone is known as color zoning, and this characteristic is particularly common in sapphires, tourmaline, and quartz. The cause of color zoning is the availability of trace elements in the crystallization process. While the presence of zoning may sometimes be unappealing, it is often beneficial when two or more colors are visible. Depending on the degree of zoning, the gem may be worth more or less than the average stone.

A gemstone’s proportions are also important. The crown of a gemstone is its upper part, while the girdle is its lower end. For round gemstones, the normal depth range is between 60% and 80%. Other measurements include the length-to-width ratio, which refers to the proportion of length to width of a stone. Overly narrow or wide gemstones of a specific shape are usually undesirable.


Gemstones are classified according to their degree of transparency. Translucent gemstones allow some light to pass through, while opaque gemstones block most light. A gemstone’s degree of translucency varies widely depending on its composition. Generally, transparent gems are faceted, while those that are opaque are cut as cabochons. Listed below are the three most common types of gemstone transparency. To learn more about the different types of transparency, read on.

The degree of transparency is a property of a substance, and is closely related to clarity. Transparent gemstones let light pass through completely, while opaque gems obstruct or scatter light. Transparent gemstones produce sharp images without distortion. In contrast, semi-transparent gemstones allow light to pass through with a faint outline. Inclusions, including tiny holes and craters, can reduce a gemstone’s transparency.


Among the questions that are frequently asked by clients is “how hard are gemstones?” To answer this question, a rough estimate of the hardness of a particular mineral can be derived by comparing it to ordinary objects. For example, a fingernail has a hardness of 2.5, a copper penny has a hardness of 3.5, and a steel file has a toughness of 6. This gives us a rough idea of the relative hardness of various gemstones.

Gemstone hardness is one of the most misunderstood properties, but it has a scientific definition in gemology. In gemology, hardness refers to the ability of a material to resist scratching. Interestingly enough, most people consider glass and feathers soft and do not consider them as hard. The truth is that both of these materials can be scratched by various hard substances. As a result, it is advisable to purchase jewelry that is made of gemstones with the proper hardness.


There are several different meanings associated with various gemstones. The official birthstone for the month of June is the pearl. It represents the moon, feminine beauty, ultimate perfection, and religious creation. For those of us born in the month of August, the birthstone is the peridot. It is a gemstone of money and good luck and is considered protective against bad dreams. You can find more information on each gemstone by browsing the Gemstone Dictionary.

Some stones are said to have specific meanings associated with them. In the case of agate, it is the birthstone of Gemini. The Moon and Mercury influence its properties, so it is the birthstone for this sign. It is also the 12th anniversary stone for people born in Gemini. It also attracts good news and enhances success in business. In addition to their various uses, gemstones have different spiritual meanings.


What is the difference between a synthetic gem and a natural gemstone? Simply put, synthetic gemstones are man-made and are created using chemical processes. Synthetic gemstones have the same chemical composition, crystal structure, and optical properties as natural gemstones, but are created in laboratories and are sold at prices comparable to natural gems. They are a great option for jewelry buyers, as they can be offered at low prices. However, before you make a decision about the value of a synthetic gemstone, you should understand what they are.

While natural gemstones are the most beautiful, they can be costly. That is why it is important to make sure to check the label of the synthetic stone to avoid being conned into buying something you don’t need. However, synthetic stones can be beautiful and impressive. Their color and density are often more intense than natural gemstones. Whether you are looking for a statement piece or a ring for a friend, knowing the difference between the two types of gems will help you make the right decision.
